1) Ask as many questions as possible -What do you know? How do you know that for sure? What might you not be seeing? What is your goal with the info
2) Are you assuming? Find all assumptions and fix them
3) Be aware of biases (argue from the opposite side)
4) Analyze your evidence hard (Where did it come from? Are they trustworthy? How was it conducted?)
5) Don’t be afraid to admit you weren’t thinking critically & revisit your old thoughts. You are a human
